can be withdrawn from the socket 14 so as to allow the block to be rocked or swung downwardly into a vertical position and by tightening up the bolt it will engage the end of the annular groove so as to hold the block into vertical position.

My improved construction of applying device which is carried by the block comprises a cylindrical head 18 which has securedto one end thereof a brush housing 19 substantially rectangular in form which is adapted to be arranged to one side of the strip, the vertical edges of the housing being cut away as shown at 20 and rounded.

Mounted within the rectangular housing 19 is a box-shaped brush back 21 carrying bristles 22 forming a brush which is adapted to contact with the face of the strip as the strip moves past the same in order to apply a coating to the face of he strip as will be later described. Secured within the box-like back 21 of the brush is an internally threaded nipple 23 throughwhich eX- tends an externally threaded nozzle 24 which is revolubly mounted in the head and carries a detachable plug 25 at its end, the orifice of which controls the discharge of liquid and this plug is threaded within the end of the nozzle and in use when coating with a certain material I use a plug with a certain size orifice and with a coating of other materials I use a plug with a different size orifice, so that I am able to control at the point of discharge the liquid being fed to the brush.

The nozzle 24 terminates at its opposite end in a tubular extension 26 having an annular collar 27, the longitudinal movement of which is limited by a shoulder 28 at one end and by a packing ring 29 at its other end, said packing ring being externally threaded and screwed into and internal- 1y threaded socket 30 by a spanner wrench'orthe like and locked into its adjusted position by a set screw 31, said ring having an oblique face adapted to be engaged by a packing 32 which is engaged by an externally threaded ring 33 threaded into the socket 30 so as to form a stufiing box for the tubular extension of the nozzle whereby as the nozzle is rotated, any leakage ofliquid is prevented.

The tubular extension carries a hand wheel 34 for rotating the same and the end of the extension is internally threaded as shown at 35 in which a plug 36 is secured'so that when the plug isremoved a wire can be passed longitudinally through the extension and nozzle in order to remove any obstruction within the nozzle.

From the construction thus far described, it will be seen that I have provided a revoluble tubular nozzle which'has a threaded portion extending through a ferrule fixed within the brush back whereby the brush can be moved towards and away from the strip so that as the brush wears, it can'be advanced untilpractically the entire length of bristles have been used.

The brush is provided with reinforcing members A to each side of the ferrule as clearly shown and described in'my companion application covering the brush and method of making the same for stiffening the bristles to form a dam to each side of the nozzle for holding the coating material fed by the nozzle inthe brush whereby I am able to use a smaller size brush and still obtain the desired result.

"The tubular extension 26 of the nozzle 24 is provided with inlet ports 37 and 38 adapted to register with internally threaded inlets 39 and 40'formed in the head in which is adapted to be screwed a threaded nipple 41 of a valve which is provided with a threaded nipple 51 connected to a coupling 52, which in turn is connected to the outlet pipe 53 of a liquid container 54 in which the liquid to be applied to the strip in its passage through the machine is placed and from which it flows by gravity to the nozzle so as to produce a fountain brush, the supply of which can be controlled by the size of the'orifice of the plug 25 and also by the valve 50. In the construction shown, the inlet 39 is closed by a plug 42 which provides means for connecting the fountain brush directly to a force feed supply as by removing the nipple 41 and substituting a plug 42 therefor, a threaded nipple of a feed pipe can be inserted within the inlet 39 and liquid coating material could be forced under pressure directly to the nozzle.

In order to mount the head so that it can be moved towards and away from the strip in its passage through the guideway, I provide a tubular support 44 which is provided with a stem 55 mounted in an opening 56 formedin the block 15, said block being split as shown at 57 and having a bolt 58 extending across the slot so as to clamp 'thestem 55in adjusted position'within the block, which allows the tubular support to be swung at an angle in respect to the guideway or the face of the strip in its passage therethrough. r

The tubular stem is formed hollow and provided with a threaded portion 59 in which works a threaded portion of a bolt 60 which is adapted to engage a cylindrical head 18 so as to clamp the P head in its adjusted position and it will be seen that by this construction the head is free to move longitudinally within the tubular support and be locked in its adjusted position and in connection with the other adjustable features, the head-can be adjusted into various angular betilted,-swung upwardly or swung into a horizontal plane so as to swing it out of the path of travel of the strip in its passage therethrough.

In the construction herein'shown I have pro vided means for detaching the liquid container from the head and so mounting the head within the cylindrical support that by loosening the bolt 60 the head can be detached from the cylindrical support whereby the brush and head can be removed and placed into any solvent so as to thoroughly clean the same.

While I have shown a gravity feed for the brush, I am, of course, aware that a force feed could be used and that various changes in the details of construction herein shown can be made T3 the spirit of my inven without departing from tion.

By constructing a brush with a nozzle disposed therein having means surrounding the. bristles to each side of the nozzle so as to stiffen the bl'iS"; tles, and I provide a dam for the coating material being fed by the nozzle, I am able to manufacture a brush of, smaller size and yet material is spread evenlyon the strip of material in its passage therethrough.

In the operation of a machine constructed guide rollers 6 and the operator forces it into the guideway formed by the guides 2 and 3 until positions, can

obtain the: same result as the bristles are supported within the housing in such a manner that the coating course, being I understood that thevalve 50 is in closed position. A strip of flooring is then placed betweenthe' it isengaged'bythe feedroll ers -5 and the strip is then forced through the guideway past-the brush. Thevalve is then-openedand asthe operator continues to "feed strips through the machine, one strip forces the other therethrough and in the passage'of these strips through the machine a coating is applied to' the face thereof, it, of course, being understood that after one strip has been moved so as to be opposite the brush thev valve 50'is opened and the brush isadjusted so as-to apply the proper thickness of coating to the strip in its passage therethrough. r,

By having the head carrying the brushhousing-adjustable; the housing and head can be adjusted towards and away from the strip and by having the nozzle revolubly mounted and operated by a hand'wheel, the operator-after the initial setting of the housing can adjust the brush itself in respect to the face of the strip by operating the hand wheel and asthe hand wheel is rotated, the box-shaped brush back with its internally threaded ferrule is caused to reciprocate within the housing. This provides not only the means for adjusting the brush to apply the proper coating to the strip, but also provides a brush in which means is provided for adjusting the same as the bristles wear whereby the fulllength of the bristies can be used and by having the brush mounted in a brush housing, I amable to use bristles of a shorter length whereby the flexing of the same is decreased whereby thelife'of the brush is greatly increased.

By employing supporting rods of diiferent lengths, I am able to position the brush atthe proper placeon themachine to apply a coating and by having thesupporting sleeve revolubly mounted in the brush and revolubly mounted in the block, I am able to swing the brush in 'a horizontal position so as to properly align the brush in respect to the surface of the strip. In mount ing the block on the supporting rod 9 so as to allow it to oscillate, the brush can be moved .vertically in order to swing it into such position that it can be readily inspected by the operator. I

From the foregoing descriptionit will be seen that I have provided a machine for coating strips of lumber having a fountain brush so mounted that it can be adjusted in respect to the face of the strip so as to apply the proper thickness of coating to the strip in its passage therethrough and while I have illustrated the nozzle and brush being disposed within the upper portion thereof so that the supply will be in the upper portion of the brush, I am aware that the nozzle can be disposed in any suitable position without departing from the spirit of my invention andthis application is a companion application of an application executed even date herewith in which I have disclosed a machine for coating strips of lumber having novel means for feeding the coating material to the fountain brush.
